Marin Conservation League - since 1934

MCL’s success at making the environment a priority in local decision-making depends on the support of our members. As a member, you play a meaningful role in safeguarding Marin County’s natural environment.


Members receive newsletters with updates on environmental issues; discounts to MCL special events; opportunities to participate in developing positions on issues; alerts on pertinent issues; and much more. Elect to give annually and we will minimize the paper mailings you receive.


"For 85 years, MCL has been a major force in local and extended environmental advocacy. I always appreciate (their) intelligent, measured approach to addressing environmental challenges." — Jared Huffman, Congressman for the 2nd District of California
